This article mainly introduces hydroxypropyl methyl cellulose in mortar. The production process of hydroxypropyl methylcellulose is mainly a polysaccharide-based ether product produced by alkalinisation and etherification of cotton fibres (domestic). It is not charged itself. And it does not react with the charged ions in the gelling material, making it stable. The price of HPMC
Reasons for adding HPMC to mortar. The production process of hydroxypropyl methylcellulose is mainly a polysaccharide-based ether product produced by alkalinisation and etherification of cotton fibres (domestic). It is not charged in itself and does not react with charged ions in the gelling material and is stable. It is also less expensive than other types
Continued about HPMC in mortar from previous article. The relationship between HPMC and mortar quality (1) The relationship between HPMC and mortar quality (2) For particle size, the finer the particle, the better the water retention. After the large particles of cellulose ether come into contact with water, the surface immediately dissolves to form a
Continued about HPMC in mortars from previous article The relationship between HPMC and mortar quality (1) The hydration capacity of the hydroxyl group alone is not enough to cover the strong hydrogen bonds and van der Waals forces between molecules. Therefore, it only swells and does not dissolve in water. When a substituent is introduced
This article introduces you to The relationship between HPMC and mortar quality mortars. Because this part is rather long, so it is explained clearly in three parts. The applications of HPMC in mortars In ready-mixed mortar, the added amount of HPMC is very low.But it can significantly improve the performance of the wet mortar and
